Well I saw this ,and stuck it out ,I watched every move ,and wondered where did the get there expertise from .I worked in a shipyard ,and had a first hand experience of the hotting lads , they never used those pipe wrenches ,I never saw any of the reamering out that was a big and often hard part of the rivetting / platers job ,I still have a hand riviting hammer .I could go on ,I think the program could have been a lot better ,but you know ,not a lot of young uns are interested ,my memories are good ,it was a hard job .
